Do you get your dog's teeth cleaned? How much does it cost?

My dog is 4 years old and I'm taking her to the vet to have her teeth cleaned. The vet considers this surgery since they will be putting her under general anesthesia. I have to take her in today for a "pre-surgery consultation" where they will draw blood. I'm just wondering if any of you have taken your dog in for teeth cleaning? Did you have to go in for a pre-surgery consultation and how much did you pay for the procedure? Thanks!
